A process configured to increase a reliability of electrical connections in a device is also disclosed.

FIELD OF THE DISCLOSURE

The disclosure relates to systems for increasing semiconductor devicereliability. The disclosure further relates to processes for increasingsemiconductor device reliability.

BACKGROUND OF THE DISCLOSURE

Electrical components are typically supported on a structure havingconductive tracks, pads, and other features. The electrical componentsare typically connected to the structure with leads. For example, thestructure may be a printed circuit board (PCB) that mechanicallysupports and electrically connects the electrical components via theconductive tracks, the pads, and the other features. The electricalcomponents are typically soldered onto the support structure through theleads to both electrically connect and mechanically fasten theelectrical components to the support structure.

However, the electrical components and the support structure are oftenimplemented in environments subjected to changes in temperature.Accordingly, the electrical components are often required to passtemperature cycle tests, thermal shock tests, and the like. In thisregard, the thermal cycling of the electrical components and/or thesupport structure has been found to negatively impact the associatedlead structure and its connections between the electrical components andthe support structure. In particular, the thermal cycling of theelectrical components and/or the support structure has been found toform defects such as cracks, fatigue features, fractures, delamination,and/or the like in the connection between the lead structure and a padon which the lead structure is connected.

For example, it has been found that the leads connecting the electricalcomponents and/or the support structure started showing cracks, fatiguefeatures, fractures, delamination, and/or the like at a lead-solderinterface during the temperature cycle tests. Moreover, the defects,such as delamination, became severely worse after 1000 cycles of thetemperature cycle test. The electrical components and/or the supportstructure are required to pass temperature cycle tests, thermal shocktests, and the like. However, the above-noted defects at the lead-solderinterface can result in the electrical components and/or the supportstructure failing such temperature cycle tests, thermal shock tests, andthe like. Moreover, the above-noted defects at the lead-solder interfacecan result in the electrical components and/or the support structuresubsequently resulting in a device failure, reducing the reliabilitythereof, and the like. For example, FIG. 21 illustrates a device 1having a lead 2 that connects to a pad 3 on a support structure 4.Additionally, the lead 2 of the device 1 includes a pad 6 for connectionof the lead 2 to an electrical component 7. FIG. 21 further illustratesthat the device 1 has experienced a defect 8 in the form of adelamination. Likewise, FIG. 22 further illustrates another device 1that has experienced a defect 8 in the form of a crack. Similarly, FIG.23 further illustrates another device 1 that has experienced a defect 8in the form of a crack. The above-noted defects such as cracks, fatiguefeatures, fractures, delamination, and/or the like in the connection cantypically have a direct impact on the reliability of the device, asystem implementing the device, and the like.

Accordingly, what is needed are systems and processes to reduce theoccurrence of cracks, fatigue features, fractures, and/or thedelamination at a lead-solder interface in electrical components and/ora support structure.

The disclosure provides systems and processes to address at least oneroot cause of cracks, fatigue features, fractures, and/or thedelamination at a lead-solder interface (failure mode). In particular,the at least one root cause of the failure mode has been found to be inpart solder fatigue during a temperature excursion.
